Structural regulation of alginate-based adsorbents based on different coordination configurations of metal ions and selective adsorption of copper ion.

To tackle the problem of developing efficient adsorbents for the selective removal of copper ions from wastewater, this investigation focused on the synthesis of Fe-GO/MMT/SA and Al-GO/MMT/SA copper ion adsorbent materials (Fe-GMS and Al-GMS), respectively, by merging two distinct metal ions (Fe(III) and Al(III)) with sodium alginate (SA), graphene oxide (GO), and montmorillonite (MMT). By introducing metal ions with different coordination configurations, the slit structure and pore density of the adsorbents can be effectively controlled, thereby enhancing the selectivity for copper ion adsorption. The results show that Fe-GMS has excellent adsorption capacity for Cu(II) compared with Al(III), and the adsorption capacity and distribution coefficient are 116.

ITPKA phosphorylates PYCR1 and promotes the progression of glioma.

Glioma is one of the prevalent malignancies, and identifying therapeutic targets for glioma is highly important.

AGK Potentiates Arterial Thrombosis by Affecting Talin-1 and αIIbβ3-Mediated Bidirectional Signaling Pathway.

Background: AGK (acylglycerol kinase) was first identified as a mitochondrial transmembrane protein that exhibits a lipid kinase function. Recent studies have established that AGK promotes cancer growth and metastasis, enhances glycolytic metabolism and function fitness of CD8 T cells, or regulates megakaryocyte differentiation. However, the role of AGK in platelet activation and arterial thrombosis remains to be elaborated.

Hierarchical Self-Assembled Polyimide Microspheres Functionalized with Amidoxime Groups for Uranium-Containing Wastewater Remediation.

Through molecule self-assembly and subsequent surface functionalization, novel uranium adsorbent AO-OB hierarchical self-assembled polyimide microspheres (AO-OBHSPIMs) were obtained by introducing the amidoxime groups into hierarchical self-assembled polyimide microspheres for the efficient and selective recovery of uranium from wastewater. The results of Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), X-ray diffraction (XRD), and nitrogen adsorption-desorption isotherm showed that AO-OBHSPIMs were a semicrystalline polymer material with self-supporting hierarchical structure and low pore volume, and they were equipped with abundant amidoxime groups. Given the recognized selectivity of amidoxime groups and their hierarchical structure, AO-OBHSPIMs exhibited excellent selectivity to uranyl ions.

Role of GPR56 in Platelet Activation and Arterial Thrombosis.

The adhesion G protein-coupled receptor GPR56 mediates cell-cell and cell-extracellular matrix interactions. To examine the function of GPR56 in platelet activation and arterial thrombosis, we generated GPR56-knockout mice and evaluated GPR56 expression in human and mouse platelets. The results revealed that the levels of the GPR56 N-terminal fragment were significantly higher on the first day after myocardial infarction than on the seventh day in the plasma of patients with ST-segment-elevation myocardial infarction.

Extracellular signal-regulated kinase-dependent phosphorylation of histone H3 serine 10 is involved in the pathogenesis of traumatic brain injury.

Traumatic brain injury (TBI) induces a series of epigenetic changes in brain tissue, among which histone modifications are associated with the deterioration of TBI. In this study, we explored the role of histone H3 modifications in a weight-drop model of TBI in rats. Screening for various histone modifications, immunoblot analyses revealed that the phosphorylation of histone H3 serine 10 (p-H3S10) was significantly upregulated after TBI in the brain tissue surrounding the injury site.

JMJD8 Is an M2 Macrophage Biomarker, and It Associates With DNA Damage Repair to Facilitate Stemness Maintenance, Chemoresistance, and Immunosuppression in Pan-Cancer.

Background: JMJD8 has recently been identified as a cancer-related gene, but current studies provide limited information. We aimed to clarify its roles and the potential mechanisms in pan-cancer.

Methods: Pan-cancer bulk sequencing data and online web tools were applied to analyze JMJD8's correlations with prognosis, genome instability, cancer stemness, DNA repair, and immune infiltration.

Intracranial Pressure after Closure of Dura Predicts Decompressive Craniectomy in Patients with Head Trauma.

This study aimed to address the risk factors of second decompressive craniectomy (DC) in patients with traumatic brain injury (TBI) who initially underwent mass lesion evacuation, but no primary DC. Patients were enrolled if they had had a hospital visit to Xiangya Hospital, Central South University with acute closed TBI from January 1, 2017 to December 31, 2019 and had undergone craniotomic mass lesion evacuation. Sociodemographic information, computed tomography (CT) information, clinical profiles, and surgical information were obtained from an electronic database.

TFCP2, a binding protein of ATF3, promotes the progression of glioma by activating the synthesis of serine.

Glioma is one of the most common malignancies. De novo serine synthesis promotes glioma progression and therapeutic resistance. Therefore, clarifying the regulatory mechanism of serine synthesis is of great significance for glioma therapy.

LHX9, a p53-binding protein, inhibits the progression of glioma by suppressing glycolysis.

Purpose: LHX9 methylation has been reported in many tumors, but its functions and related mechanisms in glioma are still unknown and need to be verified.

Methods: The protein level of LHX9 in glioma tissues was examined using western blotting and immunohistochemistry, and the functions of LHX9 in glioma cell lines were investigated using MTT and colony formation assays. In addition, the interaction between LHX9 and P53 was analyzed by immunoprecipitation, and the roles of LHX9 in cancer metabolism were explored by measuring metabolites.

Development and Characterization of High Efficacy Cell-Penetrating Peptide via Modulation of the Histidine and Arginine Ratio for Gene Therapy.

Cell-penetrating peptides (CPPs), as non-viral gene delivery vectors, are considered with lower immunogenic response, and safer and higher gene capacity than viral systems. In our previous study, a CPP peptide called RALA (arginine rich) presented desirable transfection efficacy and owns a potential clinic use. It is believed that histidine could enhance the endosome escaping ability of CPPs, yet RALA peptide contains only one histidine in each chain.

Trans-base and trans-vault low-velocity penetrating brain injury: A retrospective comparative study of characteristics, treatment, and outcomes.

Purpose: Low-velocity penetrating brain injury (LVPBI) caused by foreign bodies can pose life-threatening emergencies. Their complexity and lack of validated classification data have prevented standardization of clinical management. We aimed to compare the trans-base and trans-vault phenotypes of LVPBI to help provide guidance for clinical decision-making of such injury type.
